To. all whom ama/ y con/cern: Be it known that I, WILLIAM JONATHAN BOOTH, residing at Park Works, Congleton,

. parts -hereinafter fully described and claimed.

plete plant-or apparatus.

' 1n the accompanying drawings, Figure 1 is a side elevation, partly in section, of the com- Fig. 2 is an end view, partly in`section, of a part of the plant or apparatus shown in Fig. l; and Fig. 3 is a detail hereinafter referred to.

The improved plant or apparatus comprises a grading-machine a, a scouring-machine '6, l and a machine c for brushing and finishing thev v grain, all arrangedone under the other., as

shown in Fig. l.

The grading-machine comprises a gradingvcylinder a', carried by Va' shaft a, mounted in the frame a3, capable of being'revolved by the pulley a4. The grading-cylinder is formed with holes or perforations in different sizes or meshes and in three sets, the first `taking out dust and other fine refuse, which passes'down the chute b', the second taking out'the broken 'grain and the like, which passes down the chute b2, 4and the third allowing the good grain to pass through' the chute t to the scouring-machine, while stones, straw, and other foreign bodies tail out over the end of the cylinder and pass down the waste-chute b4; The grain is fed into the grading-cylinder through the.

chute c, and acylindrical brush c3 is mounted over and-in frictional contact with. the grading-cylinder, the object of which is to probe outand clear any ofthe holes or periorations which may become clogged or stopped.

The grain passing through the chute Zia-'enters a hopper d, leading into a casing dl', con

taining an octagonal lining d2, which is shown.

in end view, Fig.'3, and this octagonal lining is formed in two parts d d4. Through the lining and casing a horizontal shaft e passes,

furnished with radial arms e', carrying beaters e2, while on the said shaft a worm Vexis mounted`or formed just below the bottom of the hopper d for propelling the grain forward, while at 'the forward extremity of the casing or lining an openingf is provided covered.' by a hinged door f', furnished .with a projecting arm f2, carryingan adjustable balance-weight jfs, and on the farther extremity of the-shaft e a fang is mounted, contained within a fanbox g". Between the extremity of the casing d and the fan g two chutes g g3 are arranged, the chute g2 being normally closed by an automatic door g4, beneath which a dischargingchute /L is arranged, while the chute g3 communicates with thechute r', leading to the brushing and f inishingmachine, and the shaft' e is provided with a pulley e', whereby it may be revolved. A

The grain after passing through the hopper d' is fed forward by the screw or worm e3 and is beaten by the revolving beaters e2 and is drawn through the opening j' by the action of the fan, the said opening being regulated by the door` f' and weighted balance-arm f2 f3, and the good grain passes down the chutes g.3 li to the brushing and finishing machine, and the light grain passes down the chute g,- while the dust is drawn through the fan g:

The casing inclosing the grading-cylinder is connected, by means 'of a pipe j, with the front of the fan-casing, so that dust may be drawn from the saidcasing through the pipe and fan. i l

. The grain passes from the scouring-machine to the brushing and finishing machine, which is' practically 'identical in its construction to the scouring-machine with the exception that the beaters e2 are replaced by stili brushes it', and after passing through the machine the good and finished grain is delivered through 'the chute while the lighter grain passes down the chute Z'. l

The fanbox gf is furnished with an extension 'fl/z, provided with a sliding door m', which may be retained -in any required open position by means of the screw n and nuts 71,.

The scouring machine 'may be employed without the grading-machine `and brushing IOO I and Iinishing machine for cleaning and clipping oats which would be passed therethrough and treated by the beaters and delivered, the

good and heavy grain through the chute ga 5 andthe lightgrain throughthe chute g.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, isn l The combination, with a conical chamber IO/or the'grain having an outlet in the lower part of' its larger end, a fan-casing arranged at a short distance from the said'larger end,

and delivery-chutes arrangedunder thespace between the said larger end and the said cas-f l I5 ing; of a driving-shaft which'extends through 'the said chamber and fan-casing,"a fan-Wheel secured on the said shaft inside the fan-casing,

agitating devices for the grain secured on the said shaft inside the said chamber, and a hinged valve which controls the said grainoutlet and which projects over one of the said delivery-chutes which also forms the main airinlet to the eye of thefan-casing, saidvalve also operating'to deflect the grain and to prevent the air-supply being drawn through the said chamber by the fan-wheel.
